In the original Work Plan for Work Package 9 of the EISCAT_3D Preparatory Phase, an exciter design would be tested by connecting three exciter units to a stable timing system and a control computer. However, it was found to be more convenient to use one exciter unit with three channels instead. Details of the exciter can be found in Deliverable 9.1.

The triple-channel exciter unit comprises Milestone 9.3. This Milestone was reached in January 2012.
